Dwyer® Manometer reduces cost, maximizes ventilation and improves animal health. For greenhouse use, the Manometer measures pressure between your film layers so you'll know when your film is too tight or too loose. Manometers can give you early warning of any loose and locking devices or film tears before they become serious failures.

• Dwyer ® Mark II Manometer has a curved inclined vertical tube that provides higher ranges with more easily read increments at low readings.
• Portable and compact, can be moved anywhere.
• Manufactured from indestructible molded white styrene.
